5.3 Configuring an IPv6 Address for an Interface
Assigning an IPv6 address to a device on a network enables the device to communicate with the
other devices on the network.
5.3.1 Establishing the Configuration Task
This section describes the applicable environment, pre-configuration tasks, data preparation, and
configuration procedure for assigning an IPv6 address to an interface.
Applicable Environment
When a device communicates with an IPv6 device, you need to configure IPv6 address for the
interface.
An EUI-64 address has the same function as an global unicast address. The difference is that
only the network bits need to be specified for the EUI-64 address and the host bits are transformed
from the MAC addresses of the interface while a complete 128-bit address need to be specified
for the global unicast address. Note that the prefix length of the network bits in an EUI-64 address
must not be longer than 64 bits.
The EUI-64 address and the global unicast address can be configured simultaneously or
alternatively. However, the IP addresses configured for one interface cannot be in the same
network segment.
Pre-configuration Tasks
Before configuring IPv6 addresses, complete the following tasks:
l
Configuring the physical features of the interface and ensuring that the status of the physical
layer of the interface is Up
l
Configuring the link layer parameters for the interface and ensuring that the status of the
link layer protocol on the interface is Up
Data Preparation
To configure IPv6 addresses for an interface, you need the following data.
No.
Data
1
Number of the interface
2
Link-local address configured manually
3
Global unicast address and prefix length
